    ASSESSING THE GENETIC VARIABILITY IN THE FREE RANGING ASIAN ELEPHANT (Elephas maximus) POPULATION OF WAYANAD WILDLIFE SANCTUARY
    (Kerala Veterinary and animal science university, Pookode, 2015-10-31) Neethu Balakrishnan; Arun Zachariah
    Asian Elephants (Elephas maximus) have a high influence in the culture, religion and economy, but are facing extinction in the wild. The selective poaching of male elephants for ivory leads to skewed sex ratios, which result in inbreeding and a drastic decline in population size. In this study, the genetic variability of Asian Elephant (Elephas maximus) population of Wayanad Wildlife Sanctuary was assessed using microsatellites markers. The observed polymorphism was low at the tri and tetra nucleotide loci in the samples analysed (n=28). The observed heterozygosity (0.029) was lower than the expected heterozygosity (0.915) and the mean observed heterozygosity was almost half of the expected heterozygosity indicating very high occurrence of inbreeding.
